An Shi

Sichuan University professor An Shi has been awarded a patent for a tea that uses panda feces as fertilizer. Pandas only digest about 30 percent of the bamboo they eat, and bamboo, similar to green tea, contains a cancer preventative. So, considering about 70 percent of bamboo is left in the panda excrement used to fertilize the tea, the tea is supposed to provide cancer preventative effects. The tea, due to using excrement from a rare animal, could cost upwards of $69,000 per kilogram.
